This seemed very similar to what my wife and I did. We got married at my wife's church, and had our reception at a township hall. At the township hall, we rented a large tent and my wife's family has several that do catering(they didnt charge for the work, but we paid for the food). We had a few kegs of beer and all said and done, around $3000. We had around 150 people in attendence and this was 13 years ago. My wife and I rather spend the big money on a house/land then a one time party. My wife and her mom did all of the flowers and we did the decorating. However, my folks did pay for our honeymoon which was a cruise to Cancun.
